After upgrading to GNU Radio 3.10.7 on Debian 12, my SDRplay RSP1A is no longer being detected by GQRX or any gr-osmosdr applications. The device shows up in lsusb as '1df7:3010 SDRplay RSP1A' and the API 3.07 drivers install without errors.

However, when I run 'SoapySDRUtil --find', no SDRplay devices are enumerated. Downgrading to GNU Radio 3.9 resolves the issue, but I need the newer features in 3.10 for my weak-signal work.

Anyone successfully running RSP1A with the latest GNU Radio build? I'm wondering if this is a SoapySDR compatibility issue or something deeper in the driver stack.

I hit this exact issue last month. The problem is SoapySDRPlay module wasn't recompiled against the new GNU Radio ABI. You need to rebuild it from source against GNU Radio 3.10 - the packaged version is still linked to 3.9 libraries.

Same problem here with my RSP2pro. I ended up building SoapySDRPlay from the GitHub master branch which has fixes for GNU Radio 3.10. Takes about 10 minutes to compile, then everything works perfectly. The Debian packages are indeed behind.

This is why I stick with the RSPdx - much better Linux support overall. But for your immediate problem, try installing the libsoapysdr0.8-module-sdrplay3 package instead of the regular one. That version has GNU Radio 3.10 compatibility.
